A Rockwell B-1B Lancer bomber crashed in a remote area of southeastern Montana on Monday, but its four U.S. Air Force crew members survived after ejecting from the South Dakota-based aircraft, Air Force officials said.

Two pilots and two weapons system officers ejected before the bomber crashed about 9:30 a.m. near Broadus, Mont., said Col. Kevin Kennedy, commander of the 28th Bomb Wing. He said they were taken by ambulance and air to two South Dakota hospitals, but none of them suffered life-threatening injuries.

Aerial photos of the crash show a massive charred area of prairie land void of recognizable aircraft parts.
